 * \brief CTA策略基础上下文综合测试文件（修复版）
 * 
 * \details 本文件包含对CtaStraBaseCtx类的全面测试，涵盖：
 *          - CTA策略基础上下文初始化
 *          - 交易接口测试（开平仓、买卖）
 *          - 持仓管理测试
 *          - 数据获取测试
 *          - 异常处理测试
 *          - 边界条件测试
 *          
 *          修复说明：
 *          - 移除了对非虚函数的mock override
 *          - 使用简化的测试方法
 *          - 专注于可测试的公共接口
